…pipe Make stdin extraction explicit (tar -xzf -) rather than relying on GNU tar's compiled-in default archive device. Backports the fix from QuantEcon/lecture-python.myst#953 for consistency across the migrated linkcheck workflows. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Summary
Small hardening to the linkcheck workflow: make stdin extraction explicit (
tar -xzf -) when extracting the release HTML archive from thecurlpipe, rather than relying on GNU tar's compiled-in default archive device.The current form works on
ubuntu-latest(GNU tar defaults to stdin), but-f -removes the ambiguity and is more portable. Backported from Copilot review feedback on QuantEcon/lecture-python.myst#953, keeping the linkcheck download logic consistent across the migrated repos.🤖 Generated with Claude Code
